Abstract (en)
[origin: WO2008058314A1] A stairway forming system (10) includes a plurality of stacked, elongate stair riser form carriers (12-20), the carriers (12- 20) being longitudinally displaceable relative to one another. An anchoring unit (24) anchors at least a lowermost riser form carrier (12) in position relative to a substrate (26). A positioning assembly (28) is attached to at least one of the riser form carriers (12-20) and cooperates with the remaining riser form carriers for displacing the carriers (14-20) in unison relative to one other to adopt a staggered operative configuration approximating an angle of the stairway to be formed.
